AISI / SAE STEEL NUMBERING SYSTEM


  • The first two numbers indicate the alloy according the the chart below.
  • The last two numbers indicate the amount of carbon in the alloy, where the digits “10”, for example, represent 0.10% carbon.

Example AISI/SAE 1020

  • the first two digits indicate this is plain carbon steel.
  • the last two digits indicates that the steel contains approximately 0.20% carbon.

Example AISI/SAE 4340

  • the first two digits indicate this is a Nickel-Chromium-Molybdenum alloy steel
  • the last two digits indicate that the steel contains approximately 0.4% carbon
